Hi All,
After a dist-upgrade my HDTV7 Dual Express card stopped working. I managed
to get it to work before, from the logs from Dec 15:
Dec 15 23:47:47 cheetah kernel: [ 10.701054] cx23885 driver version 0.0.1 load

That was with linux-image-2.6.26-1-amd64_2.6.26-11_amd64.deb and compiled the
cx23885 module from the mercurial repo.
The current kernel is from: linux-image-2.6.26-1-amd64_2.6.26-12_amd64.deb.
I pulled the mercurial sources again did make and make install, rebooted but
I still get:
Dec 20 13:15:02 cheetah kernel: [ 11.801129] cx23885: disagrees about
version of symbol v4l_compat_ioctl32
Dec 20 13:15:02 cheetah kernel: [ 11.801133] cx23885: Unknown symbol
v4l_compat_ioctl32
I have seen this before, but I cannot figure out what is happening. I would
appreciate if someone could explain to me what is going on here. That may
reduce my frustration somewhat.
If there is some documentation on how to debug a problem like this I would be
willing to do some debug and even work on it. I suspect that the kernel
interface got updated and changes for the driver is needed. Maybe this is a
simple enough project to get started with open source. (Let me know if
not...) I have not contributed to open source yet, so please be gentle.
I tried reinstalling the old linux-image package but that now does not work
either. There must be some other software/libs that got updated from apt-get
dist-upgrade rendering the cx23885 module unusable at the present.
Any insight would be appreciated.
